Application April 15, 1952, Serial No. 282,437

This invention relates to a ladder attachment and more particularly to adevice for supporting paint buckets, brushes or other tools on a ladderrail,

In the drawing:

Figure 1 is a side view of the base or attaching plate.

Figure 2 is a side view of the base plate on an enlarged scale with therail clampin members attached thereto;

Figure 3 is a view similar to Figure 2 but showing the device clamped toa ladder rail and between two of the rungs thereof;

Figure 4 is a detail view of one of the clamping members;

Figure 5 is a perspective view of the clamping member shown in Figure 4.v

Figure 6 is a side view of the base plate with the adjusting platepivoted thereon;

Figure '7 is a side View in elevation of the device.

Figure 8 is a top plan View of the device.

Referring to the drawings, I2 represents a flat circular plate which isprovided with a continuous circular row of aperture 35 adjacent itsperiphery. A second substantially semi-circular flat plate 3'5 ofsubstantially the same radius as the plate 52 is pivotally attached toone side of the plate 12 by a pivot member 36, as clearly shown inFigure 6. The plate 31 is adapted to be held in the desired position onthe plate l2 by the engagement of the locking members 38 with certain ofthe apertures 35 in the plate I2.

The clamping means used to clamp the device on a ladder rail comprisestwo jaws l5 and i5 pivotally attached to the other side of the plate l2by hinge members each of which comprises a pair of plates ll and 2tpivotally connected together at I9. The hinge plates are slotted at [8and 26 so that the hinges may be adjustably connected to the plate l2and the jaws I5 and 15. This adjustable feature allows the device to bemounted on ladder rails of differentcrosssectional dimensions. Theplates H are secured to the plate l2 by the bolts I4, while the plates20 are connected to the jaws by the bolts iii. A plate 22 pivotallyconnected to one edge of the jaw I5 by the hinge 23 is adapted to lieflat against a side of a ladder rail and at one edge adjustably carriesa latch member made up of the plate 26, the bolt 28, and the nut 29. Thebolt 28 is pivotally connected to the plate 26- by a conventional hinge27. The inner end portion 33 of the nut 29 is reduced to fit into anobliquely arranged recess 3| formed in a keeper plate 30 secured to theouter face of the jaw I5 so that when the nut 29 i tightened the twojaws 2 Claims. (01. 248-210) will be brought into clamping engagementwith the ladder rail. The plate 26- is slotted at 25 to receive a bolt24 for adjustably mounting the plate 26 on the plate 22.

A container 40 is detachably connected to the semi-circular plate by thscrews 39 carried by this plate and passin through openings formed inthe adjacent end wall of the container.

As shown in Figure 3, the attachment may be secured to one of the facesof a ladder rail H by swinging the jaw members l5 and I5 intosubstantially parallel relation after which the plate 22 is swung overthe rail with the portion 33 of the nut 29 engaging in the recess 3|.The nut 29 is then tightened to securely clamp the jaws on the rail l Ibetween the rungs l0.

Having thus shown and described my invention, I claim:

1. A supporting attachment for use on a ladder comprising a circularflat plate adapted to be secured against the side of a ladder rail, saidplate being provided with a circular series of apertures adjacent itsperiphery, a substantially semi-circular flat plate of substantially thesame radius as the first-mentioned plate, said secondmentioned plateengaging and being pivoted to the first-mentioned plate, substantiallydiametrically disposed locking members mounted on said second-mentionedplate and adapted to be selectively engaged in certain of the aperturesin said first-mentioned plate, a container having a side wall, means todetachably secure said container to said second-mentioned plate, saidmeans comprising screws on said second-mentioned plate extending throughopenings in the side wall of said container, a pair of substantiallyparallel elongated clamping plates hinged to the first-mentioned plateand adapted to receive a ladder rail between them, means to adjustablysecure one edge of said clamping plates on said first-mentioned plate, aplate member pivoted to the opposite edge of one of said clampingplates,

a laterally extending projection on the other clamping plate, anoutwardly-opening recess in said projection, and a latch bolt on saidplate member for engagement in said recess.

2. A supporting attachment for use on a ladder comprising a flat plateadapted to be secured against the side of a ladder rail, said platebeing provided with a circular series of apertures, a second flat plateengaging and being pivoted to said first-mentioned plate, spaced lockingmemmeans to detachably secure said container to said References Cited inthe file of this patent second-mentioned plate, a pair of rectangularUNITED STATES PATENTS substantially parallel clamping plates, hingesconnecting one edge of each of said clamping ggz ggfi Dec f 1899 platesto the first-mentioned plate, a latch plate 5 831375 Polak Sept 1906pimtany cmnected the edge 1,211j906 A1bert1fi Jan. 911917 clamping plateand carrying a latch bolt, and a 1243732 Goss et a1 Oct 23, 1917 keeperplate secured adjacent to the free edge 1,339,025 Garst May 4, 1920 ofsaid other clamping plate and having a recess 10 1,353,277 Bochard 91920 to receive said latch bolt. 1,662,539 Schmidt Mar, 13, 1928
